AdaClimGreenland (June-August) 2005

AdaClim 2005Goals(1) Quantify differences in local oceanographic

conditions between the two study sites (eastern and western Greenland Sea).

(2) Determine the trophic status of the two Little Auk (Alle alle) populations.

(3) Compare the predatory efficiencies of the two

populations.

(4) Examine the breeding strategies and adult survival of Little Auks.

These trials will be a first step towards a better understanding of how Arctic marine predators react to climate change.
